Are you making your QTVisualContext shared with the context that the
QCPlugin provides? This ensures that the QTvisualContext and your
CGLContext are shared, so textures/resources are able to move between
contexts quickly.
As for the leak, you need to make sure you call QTVisualContextTask()
to service quicktime, or you will see that leak.
Another issue I had with getting QTVisualContext to work well within
my app was colorspace conversion. It looks like you are assuming ARGB
or BGRA, when you may be getting other formats. You can add hints to
your QTVisualContextCreate to add input/output and working color
spaces, but thats a nuanced topic, and possible off topic for the QC
list. I did see some improvement tuning those values.
